3M 7000144900 Flame Resistant Hook Fastener 1in X 50yd

Product Description

The 3M 7000144900 is a flame resistant, woven nylon hook reclosable fastener sold in a 1-inch wide by 50-yard roll in beige. This is the hook component of a two-part reclosable fastener system and carries no pressure-sensitive adhesive, relying instead on mechanical engagement with a corresponding loop tape. Engaged thickness is 0.15 inches. The fastener is rated for continuous use up to 250 degrees F and meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test requirements. It is preshrunk for dimensional stability. Installation is performed by sewn-in attachment to fabric substrates.

This fastener is used in aerospace, transportation, and industrial textile applications where flame resistance is a code requirement. Typical end uses include adjustable closures on garments, covers, and protective fabrics that require a clean, tailored appearance. The no-adhesive construction makes it suitable for applications that undergo repeated laundering or dry cleaning. The woven nylon construction maintains flatness and resists distortion through wash cycles.

Key Features

• Flame resistant construction meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test
• Temperature rated to 250 degrees F continuous service
• No adhesive backing — intended for sewn-in attachment
• Preshrunk nylon weave for maximum dimensional stability and flatness
• Washable and dry cleanable for repeated-service applications
• Mates with 3M SJ3418FR loop fastener tape

Compatibility

Designed to mate with 3M SJ3418FR flame resistant loop fastener. Suitable for sewn-in closure applications on flame resistant garments, covers, and industrial fabrics requiring reclosable fastening.

Installation Notes

Attachment is accomplished by sewing the tape to the fabric substrate — no adhesive activation is required. Follow the fabric and garment manufacturer guidelines for stitch type and seam allowance. Verify that all mating materials, thread, and substrates also meet the applicable flame resistance standard for the final assembly. This product is sold as hook tape only; the mating loop tape must be ordered separately.
